BLOOD AND NERVE SUPPLY OF BONE

Arteries:

• The bones are highly vascular.
• The bone is supplied with blood externally on the surface and internally on the lining of the medullary cavity.
• The surface arteries ramify over the periosteum and large blood vessels gain entrance through the nutrient foramen and branches widely along the course and on the endosteal lining  of the bone. Thus there is a network of blood vessels over the entire bone.

Veins:

• They accompany the arteries ans mostly recurrent in nature.

Nerves:

• They accompany the blood vesels. The periosteal branches are senosry.

Lymph vessels:

• They run in company with blood vessels of the marrow,forming a network under the periosteum.
